  • the connectors to be fitted in each panel are restricted, and this structure can be applied neither to a plug-type connector on which a plurality of plug pins are embedded nor to a receptacle-type connector having a contact into which the plurality of plug pins are inserted.
  • the latter connector is made up of a connector having plug pins and a contact through which the plug pins are inserted, however, the contact is made up of contact spring pieces with inverted U-shaped spring pieces, and hence this connector has a specific structure. Accordingly, it is necessary to design a connector housing and contact terminals in specific shape. As a result, the panel versus panel type connector system connector can not employ an ordinary plug-type connector and a receptacle-type connector.

  • the elastic retainer pieces are bent towards the posts.
  • the elastic retainer pieces are excessively bent, they are prone to be folded down and broken at the connecting spot between themselves and the post, but the tongue pieces are butted against the surfaces of the posts and restricted in bending before the elastic retainer pieces are excessively bent, so that the elastic retainer pieces are prevented from being broken.
  • the retainer members are preferably structured to be made up of retainer bases comprising lock grooves having diameters which are smaller than those of attachment ports of the panel and widths which are wider than a thickness of the panel, and retainer stepped parts of the elastic retainer pieces , respectively at fixed roots of the flanges.

  • the elastic retainer pieces are fixedly attached to the flanges while facing each other, if a foreign matter impinges against the retainer members from an outside, the foreign matter can be received by the posts, and it does not reach the elastic retainer pieces. As a result, it is possible to prevent the occurrence of the case where the elastic retainer pieces are pressed when the foreign matter impinges against the retainer members, thereby preventing the retainer stepped parts from being removed from the peripheral edge of the attachment port of the panel.
  • the method for attaching a connector with retainer members to be attached to a panel to another panel comprises the steps of preparing the connector as in any of the first to third aspects of the invention, and a panel having attachment ports slightly larger than a diameter of an outer periphery of the retainer members of the connector; characterized in that when the retainer members are inserted into the attachment ports of the panel against the urging of elastic force thereof, the retainer bases of the retainer members are freely engaged in the attachment ports of the panel, whereby the retainer bases are engaged with peripheral edges of the attachment ports of the panel at stepped parts of the lock groove walls and stepped parts of the elastic retainer pieces.
  • the retainer members are freely engaged in the attachment ports by the difference in diameters thereof in a peripheral external direction.
  • the retainer bases are engaged with peripheral edges of the attachment ports of the panel at the stepped parts of the lock grooves and the stepped parts of the elastic retainer pieces, so that even if the retainer bases are moved in the attachment ports and engagement areas of the stepped parts relative to the panel are reduced, the stepped parts are engaged with the attachment ports by the amount of reduction of the engagement areas, and hence the stepped parts are retained by the panel while they are complemented with each other.
  • a method of coupling a connector attached to a panel by the method according to the fifth aspect of the invention to another connector fixedly attached to another panel as in the fourth aspect of the invention is characterized in that in cases where positional displacement occurs between both connectors when both connectors are coupled with each other, the connector is coupled with another connector fixedly attached to another panel in a state where the retainer bases of the connector are freely engaged in the attachment ports of the panel, so that the retainer bases are movable in the attachment port by an interval corresponding to a difference in diameter between the attachment port of the panel and the outer periphery of the retainer bases, thereby absorbing the positional displacement between both connectors.

Since the elastic retainer pieces 34, 34 are fixedly attached to the flanges while they face each other, even if a foreign matter impinges against the retainer members 30a, 30b from outside, the foreign matter is received by the posts 31, 31 and it does not reach the elastic retainer pieces 34, 34. As a result, there doesn't occur a case where the elastic retainer pieces 34, 34 are pressed when a foreign matter impinges against them so that the retainer stepped part 34a is not removed from the peripheral edge of attachment port of the panel.
  • the retainer members set forth above are columnar or conical, they are not limited to such a shape and may be formed in an optional shape such as square pillar-shaped, or triangular pillar-shaped or the like.
  • the receptacle proper has a flat block shape, it is not limited to this shape and may be formed of a housing having an optional shape such as cylindrical, elliptical, square and the like in a sectional area which is cut orthogonal to a direction of insertion or removal of the connector.
  • the fixing position of the retainer members can be changed to not only left and right back face but also to an optional wall surface such as upper and lower wall surfaces or the like owing to the change of the shapes of the retaining members.
  • Fig. 4(A) is a plan view of a panel to which the connector of the embodiment of the invention is fitted.
  • Fig. 4(B) is a front view for explaining the relationship between a receptacle 10 and the attachment port of the panel.
  • a panel 50 has attachment ports 53a, 53b through which two retainer members 30a, 30b are inserted, and an opening 54 through which a housing 16 is inserted is defined between the retainer members 30a, 30b. Diameters of the attachment ports 53a, 53b are slightly larger than outer peripheral diameters of the retainer bases 32, 32, wherein the retainer members 30a, 30b are freely engaged in the attachment ports 53a, 53b.
  • the opening 54 is an opening through which the back housing 16 is inserted, the size of the opening 54 is set to be larger than an external shape of the back housing 16 to the extent that positioning displacement (described later) can be adjusted.
  • Figs. 5(A) to 5(C) are views each showing a state where the typical retainer member in Figs. 1 (A) to 1(D) is fitted in the panel, wherein Fig. 5(A) is a sectional view showing the state during the insertion of the retainer member into the panel, Fig. 5(B) is a sectional view showing the state of the retainer member immediately after it is inserted into the panel, and Fig. 5(C) is a sectional view showing the state where the retainer member is moved after it was attached to the panel.
  • a method of attaching both the retainer members 30a, 30b to attachment port of the panels 53 of the panel 50 is described by use of one typical retainer member 30 with reference to Figs. 5(A) to 5(C). Accordingly, the typical retainer member 30 is applicable to either the retainer member 30a or 30b according to the method of attachment thereof and engagement state thereof relative to the attachment port 53, wherein both the retainer members are the same in the state of attachment to the attachment port in function but merely different in the moving direction in a symmetrical manner.
  • the retainer member 30 when the retainer member 30 is pushed deeper into the attachment port 53 of the panel and the retainer stepped part 34a passes through the inner end face of the panel 50, the retainer member 30 is returned to an original state due to elastic force of the elastic retainer piece 34 and the panel 50 enters the interior of the retainer base 32 of the retainer member 30, so that the receptacle 10 is fixedly attached to the panel 50 by the retainer member 30 (see Fig. 5(C)).
  • the outer peripheral diameter of the retainer base 32 formed at the root of the retainer member 30 in this state is formed smaller than the diameter of the attachment port 53 of the panel so that the retainer member 30 can be freely engaged in the attachment port 53 of the panel by the difference in the diameters therebetween in a circumferential outward direction.
  • the retainer base 32 In a normal attachment state, the retainer base 32 is engaged with the peripheral edge of the attachment port 53 of the panel by the stepped part 31a of the lock groove wall and the stepped part 34a of the elastic retainer member so that the retainer base 32 is moved in the attachment port of the panel. Even if an engagement area of the retainer stepped part 34a relative to the panel 50 is reduced, the stepped part 31a is engaged with the peripheral edge of the attachment port of the panel by the amount of reduction of the engagement area, and hence the retainer base 32 is engaged in the attachment port of the panel while the retainer base 32 and the retainer stepped part 34a are complementing each other.
  • the stepped part 31a is removed from the peripheral edge of the attachment port of the panel, and the engagement area is reduced, but the retainer base 32 is sufficiently engaged with the attachment port of the panel at the other retainer stepped part 34a by the amount of reduction of the engagement area. That is, when the retainer member is moved left and right in a normal state, the stepped part is butted against and engaged with the peripheral edge of the attachment port while the other stepped part is engaged with the peripheral edge of the attachment port, thereby increasing the engagement area relative to the face of the panel, so that stable engaging state is achieved.
  • the retainer member 30 when the retainer member 30 is moved extremely towards one side so that the stepped part 31a is removed from the peripheral edge of the attachment port of the panel, the other stepped part is deeply engaged with the peripheral edge of the attachment port, thereby achieving an excellent engaging state.
  • the engaging state between the retainer member 30 and the attachment port of the panel described above can be achieved by the engagement between the retainer members 30a, 30b and the attachment ports 53a, 53b.
  • Figs. 6(A) to 6(C) are views each showing a positional relationship in a coupling state between the connector according to the embodiment of the invention and another connector, wherein Fig.6(A) is a plan view of the positional relationship in a normal state where positional displacement does not occur, Fig.6(B) is a plan view of the positional relationship in a state where the positional displacement occurs, and Fig.6(C) is a plan view showing a state where the positional displacement is absorbed.
  • a housing proper of a plug 60 coupled with the receptacle 10 is divided at the flange, as the boundary, into a front housing 61a and a back housing 61b, and a pair of retainer members 63a, 63b are formed on both sidewalls of the housing proper.
  • the back housing 61b of the plug 60 is inserted into the attachment port provided in a panel 70, and the plug 60 is firmly attached to the panel by the pair of retainer members 63a, 63b.
  • Described with reference to Figs. 6(A) to 6(C) are a method of attaching the receptacle 10, for example, an eight pole receptacle having e.g., 8 connector terminals, to the panel 50 and a method of adjusting positional displacement which occurs between the receptacle 10 and the plug 60 firmly attached to another panel 70 to be coupled with the receptacle 10.
  • the receptacle 10 for example, an eight pole receptacle having e.g., 8 connector terminals
  • the receptacle 10 is attached to the panel 50 as shown in Fig. 4.
  • the panel 50 has two attachment ports 53a, 53b into which retainer members 30a, 30b are inserted, and the opening 54 into which the connector terminals are inserted and which is disposed between the attachment ports 53a, 53b.
  • the diameter of the attachment ports 53a, 53b is formed larger than the outer peripheral diameter of the retainer base of the retainer member, e.g., by about 1. 2 mm.
  • the retainer member When the retainer base having an outer peripheral diameter of 4. 0 mm is inserted into the attachment port having the diameter of 5. 2 mm, the retainer member is freely movably engaged in the attachment port in the peripheral outward direction by the half of the difference therebetween, namely, 0. 6 mm because the outer peripheral diameter of the retainer base is formed smaller than the diameter of the attachment port by 1. 2 mm as described in the engaging state between the attachment port 53b and the retaining member 30b.
  • the receptacle 10 is fitted in the panel 50, and the same receptacle 10 is coupled with the plug 60 which is fixedly attached to another panel.
  • the plug 60 is not movable horizontally and vertically in any case shown in Figs. 6(A) to 6(C) and firmly fixedly attached to the panel 70.
  • the receptacle 10 and the plug 60 are smoothly coupled with each other such that the front housing 15 of the receptacle 10 is engaged in the opening of the plug 60 while the receptacle 10 is not moved horizontally, i.e., orthogonal to the coupling direction thereof or vertically, i.e., perpendicularly to the coupling direction at the central position in the coupling direction of both the receptacle 10 and plug 60 (position show in dotted and chain line).
  • the inclined portion 17a, 17b of the front housing of the receptacle 10 enters the chamfered surface in the vicinity of the opening of the plug 60, and the receptacle 10 is moved by the distance of the positional displacement, so that the receptacle 10 is corrected in course to a normal state, and hence both the receptacle 10 and the plug 60 are coupled with each other.
  • the receptacle 10 can be corrected in course in the same manner as set forth above. Still further, even if the positional displacement occurs not only horizontally, i.e., orthogonal to the coupling direction of the receptacle but also vertically, i.e., perpendicularly to the coupling direction thereof, it can be corrected in course in the same manner as set forth above.
  • the elastic retainer pieces of the retainer members are not broken when they are fitted into the panel, even if they are excessively bent.
  • the connector with retainer members can be fitted in the panel while ensuring strength and stability not to remove from the panel.
  • the connector when the connector is fitted to another connector which is fixedly attached to the panel, they can be connected to each other without laboring while the error of the attachment positions of the panels which occurs between both the connectors can be automatically adjusted.
